Hey guys!! I have a quick question that I really need an answer to!

Okay so I had my period and the day I got off   I had sex, 4 or 5 days after I had sex I woke up sick puking and just didn't feel good at all, I haven't thrown up since I was like 10! But I haven't been sick since that day. Is their any way that I could be pregnant? My husband and I have been try to conceive for about 5 months, my husband is also a diabetic and we have read that it can be harder to conceive?
